According to host and molecular biologist Torah Kachur, there's no such thing as waste — only wasted resources. Scientists are transforming what has previously been seen as garbage into valuable materials that can be used in surprising (and sometimes profitable) ways.
This CBC Radio series breaks down complex problems into manageable pieces with practical solutions. Each episode features scientists from around the world, local stories and a Waste Warrior who is pushing the boundaries to repurpose his or her personal waste.
